STRAINER.

Specification of Letters Patent.

Patented May '7, 1907.

Application filed June 30, 1906. Serial No. 324,257.

To all whom it may concern,.-

Be it known that I, CHARLES RILEY Asn- MEAD, a citizen of the United States, residing at Nevada, in the county of Vernon and State of Missouri, have invented new and useful Improvements in Strainers, of which the following is a specification.

This invention relates to strainers designed especially for use in straining milk,

and has for its objects to provide a comparatively simple, inexpensive device of this character in which one or more straining members may be employed and this without perceptibly varying the speed of action of the device, one wherein the straining members or cloths may be conveniently applied or removed, and one which will be of a thoroughly sanitary nature, permitting ready cleansing of the various parts of the device.

With these and other objects in view, the invention comprises the novel features of construction and combination of parts more fully hereinafter described. i

In the accompanying drawings; Figure l is a central, vertical section through a strainer embodying the invention. Fig. 2 is a similar view showing a slightly modified form of the device. Fig. 3 is a perspective view of one of the clamping rings as employed in Fig. l. Fig. 4 is a perspective view of the inner clamping ring, as employed in Fig. 2.

Referring to the drawings, 1 designates a sheet meta straining vessel or funnel provided with a reduced, tubular throat 2 having an open, lower discharge end over which is applied a reticulated straining member or sheet 3 composed preferably and in accordance with the invention of cheese cloth or analogous loosely woven fabric, said straining sheet being detachably secured to the vessel by means of an outer clamping member or ring 4 fitted onto the throat 2 over which the straining material is extended prior to application of the ring. There is also applied to the vessel 1 at the upper end of the throat 2 an upper straining member or sheet 5 composed of cheese cloth, as in the instance of the lower straining member 4, and detachably secured in place by means of a clamping member or ring 6 fitted within the throat 2, the ring 6 being, as seen in Fi l, of a width equaling about substantia y half the length of the throat 2, while, as shown in Fig. 2, the ring is of a Width approximately equaling the total length of the throat. There may also be employed in connection with the vessel, as seen in Fig. 1, a third or intermediate straining member or sheet 7 arranged midway between the members 3 and 5, said member, which is composed of cheese cloth orv other pliable washable fabric, as in the instance of the strainers 3 and 5, being detachably secured by means of a ring 8 fitted within the throat and of a width equaling substantially half the length of the latter, as in the case of the ring 6, beneath which the ring 8 is disposed.

Fn practice, the milk or other liquid to be strained, is poured into the upper end. of the vessel or funnel 1, as usual, and percolates through the straining member or members, it being understood, of course, that in practice, the lower straining member 3 may be employed alone or in conjunction with the principal straining member 5, as seen in Fig. 2, or together with the straining members 5 and 7, as seen in Fig. 1. After the device has been used, the straining members or cloths 3 may by removing the retaining rings, be readily detached from the vessel to permit cleansing of the latter', and also of the cloths, it being apparent that owing to the strainers proper being com osed of washable fabric and being detachab y connected with the vessel the requisite sanitary conditions are insured and convenient cleaning of the parts or ready and inexpensive renewal of the cloths permitted.

It is obvious that the number of cloths may be increased as desired by lengthening the throat 2 and decreasing the width of the inner clamping rings.

Having thus described my invention, what I claim is l. A strainer comprising a vessel having .an open, wholly unobstructed tubular throat,

a lower straining member com osed of a pliable, reticulated fabric app ied over the lower end of the throat, a removable clamping band fitted on the outside of the throat for detachably securing the fabric in place, an inner clamping band removably fitted within the throat and a sheet of pliable, reticulated fabric applied over the u per end of and clamped in place within the throat by means of the band and constituting an upper straining member serving in conjunction with the lower member as the sole means for straining the liquid.

2. A strainer comprising a vessel having an open, Wholly unobstructed tubular throat, a lower straining member composed of a pli- IOO IIO

lo constituting upper and intermediate straining members serving in conjunction with the lower straining member as the sole means for straining the liquid.

In testimony whereof, I aix my signature in presence of two witnesses.
